The measurement of the maximum circumference of the head is a part of the routine physical examination of any baby, just as much as examination of the heart, chest, and abdomen, as examination of the hips for subluxation, of the urine for phenylpyruvic acid, and ofthe hearing after the age of 3 or 4 months, The importance of measuring the head circumference lies partly in the early detection of...

OBJECTIVES To describe the head growth of children according to maternal and child HIV infection status. DESIGN Longitudinal analysis of head circumference data from 13 647 children followed from birth in the ZVITAMBO trial, undertaken in Harare, Zimbabwe, between 1997 and 2001, prior to availability of antiretroviral therapy (ART) or cotrimoxazole prophylaxis. METHODS Head circumference wa...

To determine regional percentile values and compare them with currently used national and international curves, we determined the birth weight, height and head and chest circumference of 3688 term neonates born in a state hospital in the Anatolian part of Istanbul, Turkey. Mean birth weight, height and head and chest circumference were 3334 (SD 494) g, 48.3 (SD 2.2) cm, 34.4 (SD 1.3) cm and 32....

This paper explores the fitting of multi-level models to growth data over a wide age range using a new class of extended spline models. These extend conventional splines based on a '+' function representation by allowing variable order functions and by including fractional polynomial terms. The work focuses on modelling human growth in height and head circumference with example data sets. The p...

OBJECTIVE To determine the effects of prenatal cocaine exposure on child development. METHODS This prospective, longitudinal study recruited 154 pregnant cocaine users who were matched on race, parity, socioeconomic status, and perinatal risk to 154 noncocaine users. Drug use status was determined by maternal history and urine screening. At 3 years of age, the child subjects were assessed by ...

BACKGROUND The measurement of head circumference (HC) is widely used in clinical and research settings as a proxy of neural growth. Although it could aid data collection, no studies have explored either the reliability of adult self-measurements or parental measurements of young children. This study therefore aimed to examine whether adult self and parental measurement of HC constitute reliable...

A cross-sectional study of adolescent growth was undertaken among the Brahmin girls residing in rural and urban areas of Sagar districts, Madhya Pradesh to evaluate the urban-rural differences. Six anthropometric measurements, such as weight, stature, sitting height, head circumference, upper arm circumference and chest girth are taken into consideration. Though the urban girls show consistentl...
